目的：评价经静脉置入Amplatzer封堵器治疗继发孔型房间隔缺损(ASD)的疗效。方法：24例患者术前经多普勒超声心动图检查ASD直径为6～30(18.96±7.03)mm。在透视及经超声心动图引导下经静脉置入Amplatzer封堵器闭合ASD。 结果：24例ASD直径的球囊测量值为15～36(26.25±7.57)mm,选择的封堵器直径为14～36(26.52±7.15)mm。24例封堵器置入均获得成功 ，术中无并发症， 1例在术后第3天出现Ⅱ度Ⅰ型房室传导阻滞，2周后恢复 。7例术后即刻超声检查显示微量残余分流，术后1周复查均无分流。结论：经静脉置入Amplatzer封堵器治疗ASD是一种有效的非外科手术方法 。“,”Objective:To evaluate the efficiency of transvenous oclusion of secundum atrial septal defect (ASD) using Amplatzer occluder.Method:There were 24 patients ( 6 male and 18 female, mean age 26.6 years). Echocardiography confirmed the ASD with a diameter of (18.96±7.03)mm (ranging from 6 to 30 mm). All patients with ASD were treated using Amplatzer occluder under guiding fluoroscopy and echocardiography through the percutaneous procedure.Result:The mean balloon stretched diameter of the ASDs in 24 patients was 15～36(26.25±7.57)mm.The mean diameter of the occluder selected was 14～36(26.52±7.15)mm.The successful rate of placement of the Amplatzer occluder was 100%. No complication was found during the procedures and during follow up. Trivial residual shunt was found in 7 patients immediately after the procedures， and there was no residual shunt 1 week after the procedures and during follow-up.Conclusion:Transvenous closure of secundum ASD using Amplatzer septal occluder is an efficient nonsurgical method.
